Well folks the D1 is in and it went really well. We ended up with 475whp and 440 rwtq. First pull was at 500 whp then we put bigger pulley on to limit the boost to 9psi. Had 11 psi on the 500whp pull. I have a little idle surge and the car stalled on me a few times but hopefully it’s no big deal maybe just a tweek on the tune idk. Anyway car is a beast now can’t believe the difference can’t wait to forge the bottom end in the winter.
